Multi-Trophic Interactions in a Forest Biodiversity Experiment in China

MultiTroph.jpg

DFG FOR 5281 MultiTroph_9 positionsnew.pdf

We offer nine positions within the newly established DFG Research Unit MultiTroph FOR 5281.

The Research Unit MultiTroph is part of the Biodiversity-Ecosystem Functioning China (BEF-China) research platform. The platform was established in 2008 by Chinese, German and Swiss researchers (https://bef-china.com) and comprises the worldwide largest tree diversity experiment.

MultiTroph aims to identify mechanisms underlying the relationships between biodiversity and ecosystem functions across different trophic interactions along the experimental tree diversity gradient of BEF-China. The ultimate goal is to connect the different interaction types to large food webs in the context of tree diversity loss. Prof. Dr. Alexandra-Maria Klein from the University of Freiburg, (www.nature.uni-freiburg.de) leads the Research Unit in collaboration with Prof. Dr. Chao-Dong Zhu, Institute of Zoology, Chinese Academy of Sciences, Beijing, China (http://english.ioz.cas.cn) and with the German Centre for Integrative Biodiversity Research Halle-Jena-Leipzig (iDiv, www.idiv.de).

The starting date for all positions is October 1st, 2022 with some flexibility if necessary.

The submission deadline for applications is July, 15 th 2022.

1) Six research positions (f/m/d, 13 TV-L, 65%) for a period of 4 years aiming for a PhD degree

PhD 1 Wood decomposition and decomposer interactions Subject: MultiTroph_SP1_PhDposition Prof. Dr. Heike Feldhaar, University of Bayreuth, Dr. Simon Thorn, University of Würzburg. The PhD student will be enrolled at the University of Bayreuth.

The candidate will study saproxylic insect communities. The candidate will extend previous work by including tree diversity as a driver of saproxylic insect communities and the entailing decomposition process. The goal is to disentangle the direct effects of tree diversity on decomposer communities from indirect effects mediated through environmental changes affecting the local species pool, thereby altering community assembly processes in dead wood or interactions between decomposers and organisms of other trophic levels.

Submit application documents to Feldhaar@uni-bayreuth.de

PhD 2 Trophic-interaction and soil-erosion effects on soil-plant stoichiometry Subject: MultiTroph_SP2_PhDposition Prof. Dr. Yvonne Oelmann, Prof. Dr. Thomas Scholten, Dr. Steffen Seitz, University of Tübingen The candidate will study nutrients and their stoichiometry in soil, soil microorganisms and in plants. The candidate will continue the long-term monitoring of soil properties within BEF-China and study the influence of tree diversity on lateral matter transport by erosion including the redistribution of nutrients and other aboveground surface components like litter, pollen, plant debris, and organisms. The aim is to resolve whether higher trophic levels, for example soil microorganisms that consume tree litter, share the same responses to tree diversity as lower trophic levels and whether this is linked to erosion. Submit application documents to yvonne.oelmann@uni-tuebingen.de

1 PhD 3 Plant-herbivore-predator food webs, stoichiometry and functions Subject: MultiTroph_SP3_PhDposition Assoc. Prof. Dr. Jana Petermann, University of Salzburg, Prof. Dr. Andreas Schuldt, University of Göttingen. The PhD student will be enrolled at the University of Salzburg.

The candidate will study plant-herbivore-predator arthropod food webs and will extend previous work in BEF-China by including multiple trophic levels and by linking these multitrophic communities and their interactions with biomass distributions and stoichiometry to enable an analysis of trophic pyramids and energy-based networks. The student will use classic collection techniques in the field, morphological species identification (assisted by barcoding approaches) and will study nutrient stoichiometry from trees to herbivorous insects and predatory arthropods.

PhD 4 Linking cavity-nesting bee and wasp food webs to other trophic interactions Subject: MultiTroph_SP4_PhDposition Prof. Dr. Alexandra-Maria Klein, Dr. Felix Fornoff, University of Freiburg, Dr. Manuela Sann, University of Hohenheim. The PhD student will be enrolled at the University of Freiburg.

The candidate will generate and analyse interaction networks of cavity-nesting bees and wasps including their food resources and natural enemies using DNA barcoding and metabarcoding approaches. The candidate will use reed nests and layer nests to continue our long-term monitoring of trophic networks with direct feeding observations. The candidate will build up a reliable DNA barcoding approach that serves as the basis to establish high-resolution metabarcoding of cavity-nesting Hymenoptera food webs. Submit application documents to alexandra.klein@nature.uni-freiburg.de

PhD 5 Trophic interactions across tree regeneration stages Subject: MultiTroph_SP5_PhDposition Prof. Dr. Alexandra Erfmeier, Prof. Dr. Tim Diekötter, Kiel University The candidate will study seed predation and herbivory across tree regeneration stages with an entomocentric view of the Janzen-Connell hypothesis. By aiming to identify generalist and specialist agents of seed predation and seedling herbivory, this subproject will add a decisive component of the trophic network in forests. The candidate will quantify regeneration stages as well as pre- and postdispersal seed predation and seedling herbivory of selected tree species with observational and experimental approaches in the field. Methods will include seed traps, bagging of fruits and seed cards to study seed predation, quantification of herbivory and recruitment success for selected tree species, and molecular techniques to identify insect agents delivering these functions.

PhD 6 Trophic interactions and ecological functions of ants Subject: MultiTroph_SP6_PhDposition Dr. Michael Staab, Technical University Darmstadt, Prof. Dr. Heike Feldhaar, University of Bayreuth. The PhD student will be enrolled at the Technical University Darmstadt.

The candidate will quantify ant diversity and trait distribution to functionally characterize ant communities in the BEF-China experiment. To investigate realized trophic niches, the candidate will perform resource-choice experiments and measure δ 15 N isotope values. By integrating across components of biological organization in a key arthropod taxon, the research will unravel how the interplay among tree diversity, ant diversity, trait distribution and trophic interactions influences forest ecosystem functionality.
